Ok, this is very hard for me to actually type out but here goes... I had sex with my sisters DP. That's it, out now. It was a long time ago, I was young, and drunk, no excuses really though. I'm starting to feel very paranoid. Every time I can't get hold of her (like at the mo), I think that she has found out and that will be the end of everything. We are usually quite close but sometimes she just doesn't return my calls/texts/emails.I have been trying to call for a few days with no response and am feeling really sad now. I know she is ok as our brother said so. I have thought a lot about teling her in the past but decided that it would be more to ease my conscience than help her, and as time goes by it gets harder. I just keep crying and I can't even tell DH what's wrong with me so he thinks I'm losing it. I don't know what I want anybody to say, I guess I just needed to get it out so sorry for the rant.
